Translation guide
In Japanese, the concept of a home telephone is typically expressed by specifying a landline or a phone at one's house. The most common and natural way is 家の電話 (ie no denwa), literally 'house phone'. Other options include 自宅の電話 (jitaku no denwa) for a more formal tone, or simply 固定電話 (kotei denwa) meaning 'landline'. Note that in modern Japan, many people no longer have a landline, so context matters.
